BARBER-CHAIR.

SPECIFICATION forming part of Letters Patent No. 637,715, dated November 21, 1899. Application filed February 23, 1899. Serial 110,706,485. (N0 model.)

To otZZ whom it may concern:

Be it known that I, FRANCIS DE FONTES, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Barher-Chairs, of which the following is a specification.

This invention relates to a barbers chair, and has for its object to provide improved mechanism and construction for effecting various adjustments of the body, back, and footrest of the chair.

The invent-ion is illustrated in the accompanying drawings, in which Figure l is a verticalelevation of the chair and shows two positions of the parts, one in full lines and the other in broken lines. Fig. 2 is a vertical section of the base center and a part of the revoluble seat-support, taken on the line 2 2 of Fig. 5, whichis in atransverse direction from the line on which Fig. l is taken. Fig. 3 is a vertical section of the base center and a part of the revoluble seat-support, taken on the line 3 3 of Fig. 5, being in a transverse direction from that shown in Fig. 2. Fig. 4c is a rear view of the depending part of the leg-rest, looking forward. Fig. 5 is a top view of the base center. Fig. 6 is a view of the foot'rest detached, showing the side that would be seen when seated in the chair.

The letter Adesignates the feet of the base, and A the base center to which the feet are attached. This base center is hollow in a vertical direction and at its bottom'has a contracted portion a, with "a round pivot-hole through it for the tubular vertical spindle B. At the top of thebase center and made fast thereto is a circular cap-plate b, having a round pivot-hole in its center also for the spindle B and provided with holes 0, arranged in a circle around the spindle-hole. The revoluble seat support 0 has the depending spindle B attached. The seat-support rests upon the circular cap-plate b. It will be seen that the seat-support C may readily turn in a horizontal plane. The seat-support has at two opposite sides upright standards d, which have pivots d, that snpportthe chair-seat frame D, thus allowing the latter to tilt, as indicated by broken lines in Fig. 1. The seat-support C at the rear has an upward-curved rigid arm 0, provided at its top with a slotted guide e and two rollers or pins'e, extending across the slot.

The back E of the chair is pivoted at each side by pivot-pinsfto rear-curving arms'g on the side arms F, and the said back carries at its lower end a downward-curved rigid arm h, which passes freely in the slotted guide 6 of the arm 0. This down-curved arm It also passes between the said cross-pins e and at its lower end has a hook h, which serves to limit the forward tilt of the back E on its pivots f by engaging one of the said pins 6'. By this construction when the seat-support C and back of the chair are tilted backward the relative position of the back with respect to the seat is automatically changed.

The chair-seat frame D at its front and lower side has a downward-curved rack-bar 'i, and a pawl-lever G has three arms jj 7' the lower arm j being secured by a pivot-pin k to the revoluble seat-support U, occupying a slot 0 in said support, the upper arm jserving as a pawl to engage the teeth of the said curved rack-bar 1 and the rear projecting arm 3' extending directly over the upper end of the tubular vertical spindle B, where it is engaged by a rod 1, that extends down through the said spindle. The lower end of this rod Z is connected with a treadle-lever H, located below the base center A and within the space circumscribed by the spreading feet A. The treadle-lever H is pivoted by a joint m to a lateral arm attached to the lower end of the tubular spindle B. -A suitable spring at is under the rear projecting arm 3' of the pawllever and normally presses said arm upward,

stop-pin serves to hold the seat-support and chair-seat from rotating and by its adj ustment in difierent holes 0 will permit of fixing the chair-seat partly turned in any position.

7 bar 71, pawl-lever G, vertical rod Z, tubular spindle B, and treadle-lever H will all revolve down sidebars J and a cross-bar J, 'connecting the two. .A vertical leg-rest L and hori- "zontal platform N are rigidly connected and form a right angle, as shown in Fig. 1. The 1 leg-rest L is attached between the two side bars J by pivots t, and said leg-rest hasno 7 connection with the'chair-seat frame other Q than through the pivots 15.

A horizpntalrock-shaft 19 has two bearings,.

one at g on an upward-curved arm I, which projects fromthe side of the revoluble seat; support 0, and the other bearing g on top of f the seat-support. 'The outer end of the rockshaft phas a crank-arm p, which has position outside of theseat-frame D. This rock l shaft has a cam "1', which takes under a flanged head 0 on the stop-pin and serves to raise the latter and disengage it from the hole cit may be occupying in the circular cap-plate b... A

spiral spring s isaround the stop-pin cand bears downward on a cross-pin s, which extends through the stop-pin, and thus the said 1 spring 3 keeps the stop-pin normally pressed down. By throwing the crank-arm 1) toward the front to its farthest extent the stop-pin 3 c may be raised in order to turn the chair on its spindle B. It is to be understood that the seat-support O,seat-frame D, with its racktogether on the base center A.

rigidly-fixed depending frame comprising two theleg-rest L is connected with the seat-supportC by alink-rod ac, whose end, is jointed to the leg-rest by a pin w and'to. the'support by a pin m .ThisIlink-rod w serves to tilt the leg-rest relative to the down side barsJ when the chair-seat frame D and said side bars are tilted backon pivotsd. restin the present instance has a slot 11, which The top of the legmakes room for the curved rack-bar on the chair-seat frame when the chair-body is tilted back, as in broken lines in Fig. v v At the front edge of the horizontal platform N is a joint to, by which the foot-rest P is pivoted. This foot-rest consists of a suitable cushioned bar or roller mounted on two prongs P-',..approximately. V-shaped.' The united lower ends of'these prongs have ears to, which form part ofthe said joint. A downwardprojecting arm w is rigidly attached at the united ends of the prongs P, and said arm extendsdown from the joint and-below the horizontal platform N. A link-rod Q, below said platform, connects the down arm w of the foot-rest with the cross-bar J of the rigid depending frame. The construction here described-and shown has the eifect to place'the foot-rest P in a certain relative position with respect to v the leg-rest L when the chair is not tilted, (see full lines in Fig. 1;) but when I the chair is tilted on its pivots d then the position of the foot-rest'P with respect to the leg-rest L is changed and is farther'away from r the latter, as indicated by broken linesin the The upper end of 1 stretched at full length may have the footrest come at the desired distance to properly support the legs.

. The rock-shaft 19 has another cam y, which bearsupon the rear projectingarm j of the pawl-lever G. This cam is inoperative when the rock-shaft turns forward in the direction to work the other cam 'r'. vWhen turned forward in the inoperative position, a lugy on the cam comes in contact with the top of a standard zQand is thereby prevented from turning any farther; but when the rock-shaft turns in the opposite direction-z'.' e., backwardthe cam 11 forces down the arm j of the pawllever and releases the pawl end j from the rack bart'." When turned in the backward direction, the rock-shaft and cam 'ry-have no effect on the stop-pin 0. Thus the rock-shaft and cam y will serveas a substitute for the treadlelever mechanism.

Having thus described my inventionywhat I l f I claim as new, and desire to secure by Letters The chair-seat frame D at the front has a v1. In a chair the combinationofa seat-support, 0, having at opp'ositesides an upright standard, 01; anupwa'rd curved rigid arm, ,0, attached at the rear of; the seat-support and said arm provided at its top with a slotted guide, e, and two pins extending across-the slot; a chair-seat frame secured bypivots, d, to the said two upright standardsand having side arms, F: a back, E, pivoted. to the said side arms; and a downward-curved arm, h, attached by itsiupper end to the pivoted back and passing freely in the said slotted guide and provided at its lower end with a hook, h,

whereby the relative position of the back with respect to the seat is automatically changed when the chair is tilted, sub'stantiallyas described. V
